Background: Acute lymphoblastic leukemia (ALL) is the most common form of childhood cancer leading to cancer-related death in children. Most infants with ALL harbor recurring structural chromosomal rearrangements that are important initiating events in leukemogenesis but are insufficient to explain the biology and heterogeneity of the disease. Mixed-lineage leukemia-rearrangement (MLL-rearrange...

Vancomycin is a glycopeptide antibiotic which is commonly used to treat methicillin-resistant staphylococcal infections. It is commonly used in pediatric oncology wards for children with febrile neutropenia. We report a very rare side effect of vancomycin induced myopathy in a child with acute lymphoblastic leukemia. To the best of our knowledge, this is the first case reported from Oman.

Cytogenetics study using combination of conventional cytogenetics and fluorescent insitu hybridization was carried out in 171 pediatric acute lymphoblastic leukemia patients subgrouped to B-ALL (n=126) and T-ALL (n=45) by bone marrow morphology and immunophenotype. The chromosomal aberration frequency in B-ALL and T-ALL was 79% and 71%, respectively. TEL/AML1 translocation was detected in 28% o...

Hemophagocytic lymphohistiocytosis (HLH) is a rare inflammatory condition with tissue destruction due to abnormal immune activation. We present a series of 2 cases of cytomegalovirus-induced HLH in children during maintenance chemotherapy for acute lymphoblastic leukemia. These cases emphasize the importance of considering secondary HLH in this high-risk subset of pediatric patients.

Heat shock protein 27 (Hsp27), a member of the heat shock protein (Hsp) family, is critical in the regulation of cancer development, progression and chemotherapy resistance. However, the role of Hsp27 in the pathogenesis of pediatric acute leukemia (AL) remains unknown. In this study, we evaluated the expression levels of Hsp27 in bone marrow samp...

abstract background: varicella is a highly contagious and dangerous disease especially in immunocompromised patients. children with cancer are at increased risk of severe illness and may fatal cases occur. vaccination from vzv ( varicella zoster vaccine) infection can be safe, immunogenic, and effective in children with leukemia who meet the criteria and are at the risk of serious disease or de...

Infiltration of the central nervous system is a severe trait of T cell acute lymphoblastic leukemia. Inhibition of CXC chemokine receptor 4 significantly ameliorates T cell acute lymphoblastic leukemia in murine models of the disease; however, signaling by CXC chemokine receptor 4 is important in limiting the divagation of peripheral blood mononuclear cells out of the perivascular space into th...
